Sharing the LUOV: Threshold Post-Quantum Signatures
cryptographic protocols linear secret shared schemes
2019/9/19
We examine all of the signature submissions to Round-2 of the NIST PQC ``competition'' in the context of whether one can transform them into threshold signature schemes in a relatively straight forwar...
Post-Quantum Variants of ISO/IEC Standards: Compact Chosen Ciphertext Secure Key Encapsulation Mechanism from Isogenies
Post-quantum cryptosystems Isogeny-based cryptosystems CSIDH
2019/9/17
ISO/IEC standardizes several chosen ciphertext-secure key encapsulation mechanism (KEM) schemes in ISO/IEC 18033-2. However, all ISO/IEC KEM schemes are not quantum resilient. In this paper, we introd...
Quantum Algorithms for the Approximate k-List Problem and their Application to Lattice Sieving

Homomorphic encryption Quantum cryptography Information-theoretic security
2019/9/16
Homomorphic encryption (HE) schemes enable processing of encrypted data and may be used by a user to outsource storage and computations to an untrusted server. A plethora of HE schemes has been sugges...

2019/9/16
In this work we analyze the impact of translating the well-known LLL algorithm for lattice reduction into the quantum setting. We present the first (to the best of our knowledge) quantum circuit repre...
Information Conservational Security with “Black Hole” Keypad Compression and Scalable One-Time Pad — A Quantum Intelligence Approach to Pre- and Post-Quantum Cryptography
Pre- and Post-Quantum Cryptography Scalable One-Time Pad (S-OTP) Information Conservational Security (ICS)
2019/8/14
Whereas it is widely deemed impossible to overcome the optimality of the one-time pad (OTP) cipher in pre- and post-quantum cryptography, this work shows that the optimality of information theoretic s...
